The Science of Sanitary Pads: How They Work to Keep You Clean and Dry

Sanitary pads are a necessary product that women use to manage their menstrual flow. They come in different shapes, sizes, and absorbencies, but all serve the same purpose of keeping women clean and dry during their periods. In this blog post, we will explore the science behind how sanitary pads work to keep you comfortable and confident during your menstrual cycle.

1). The anatomy of a sanitary pad

A typical sanitary pad consists of several layers of material that work together to provide absorbency, leak protection, and comfort. The top layer is usually made of a soft, cotton-like material that is gentle on the skin. This layer is designed to quickly wick away moisture from the body and into the absorbent core of the pad.

The absorbent core is the part of the pad that soaks up the menstrual fluid. It is usually made of a mixture of wood pulp and superabsorbent polymers (SAPs). SAPs are tiny beads that can absorb many times their weight in liquid, which helps to keep the pad thin and discreet while still providing maximum absorbency.

2). How sanitary pads prevent leaks

Sanitary pads are designed with leak protection in mind. The absorbent core is surrounded by a barrier layer that helps to prevent leaks by directing the flow of menstrual fluid into the core. The barrier layer can be made of different materials, such as plastic or a waterproof coating, depending on the brand and the level of absorbency.

Some pads also have wings like- Keep Going Sanitary Pads that wrap around the sides of the underwear to provide additional leak protection. The wings have an adhesive backing that sticks to the underwear, keeping the pad securely in place.

3). The importance of breathability

Breathability is an essential factor when it comes to choosing the right sanitary pad. A breathable pad allows air to circulate, which helps to prevent irritation and odour. It also helps to keep the skin feeling cool and comfortable.

Many modern sanitary pads are designed with breathable materials, such as cotton, to provide maximum comfort and breathability.

4). The environmental impact of sanitary pads

Sanitary pads have a significant environmental impact, as they are not biodegradable and can take hundreds of years to decompose in landfills. However, there are now eco-friendly options available, such as pads made from organic cotton or biodegradable materials.

5). How to choose the right sanitary pad for you

Choosing the right sanitary pad is essential for maximum comfort and protection during your menstrual cycle. Factors to consider include the level of absorbency, the shape and size of the pad, and the material it is made from. It is also important to consider any skin sensitivities or allergies you may have.


Sanitary pads are an essential product for women, providing comfort and protection during their menstrual cycle. By understanding the science behind how they work, you can make an informed choice when it comes to choosing the right pad for you. Whether you prefer a thin, discreet pad or one with maximum absorbency and leak protection, there is a sanitary pad out there that will meet your needs. Remember to choose a breathable, eco-friendly option if possible to reduce your environmental impact and stay comfortable all day long.
